IOS提示控件UIActionSheet,UIAlertView

iphone中常用的消息提示控件，就是UIActionSheet和UIAlertView了，在Web开发中，UIActionSheet就像是confirm()，而UIAlertView就像是alert()一样

UIActionSheet

UIAlertView

但在iphone中，这两个控件的功能可以自定义

定义两个控件事件方法

1. #import <UIKit/UIKit.h>
2. @interface ViewController : UIViewController
3. - (IBAction)showActionSheet:(id)sender;
4. - (IBAction)showAlertView:(id)sender;
5. @end

实现事件

1. - (IBAction)showActionSheet:(id)sender
2. {
3. UIActionSheet *showSheet = [[UIActionSheet alloc] initWithTitle:@"提示信息" delegate:self cancelButtonTitle:@"取消" destructiveButtonTitle:@"确认" otherButtonTitles:nil];
4. [showSheet showInView:self.view];
5. [showSheet release];
6. }
7. - (IBAction)showAlertView:(id)sender
8. {
9. UIAlertView *alterView = [[UIAlertView alloc] initWithTitle:@"提示信息" message:@"啊啊" delegate:self cancelButtonTitle:@"取消" otherButtonTitles: nil];
10. [alterView show];
11. [alterView release];
12. }

UIActionSheet委托代码 ，当点击确认后，弹出UIAlertView窗口提示信息

1. - (void) actionSheet: (UIActionSheet *) actionSheet
2. didDismissWithButtonIndex:(NSInteger)buttonIndex
3. {
4. NSString *msg = nil;
5. if (buttonIndex != [actionSheet cancelButtonIndex]) {
6. msg = [NSString stringWithString:@"你选择了确认"];
7. }else {
8. msg = [NSString stringWithString:@"你选择了取消"];
9. }
10. UIAlertView *alter = [[UIAlertView alloc] initWithTitle:@"提示信息" message:msg delegate:self cancelButtonTitle:@"取消" otherButtonTitles: nil];
11. [alter show];
12. [alter release];
13. [msg release];
14. }
